步驟403，接收端設備接收發送端設備發送的至少一組波束訊息。Step 403: The receiving device receives at least one group of beam messages sent by the sending device.

相應的，接收端設備接收發送端設備通過專用訊號或廣播訊號發送的該至少一組波束對應訊息。比如，當發送端設備是接入網設備時，接收端設備可以通過專用訊號或廣播訊號接收該至少一組波束對應訊息；當發送端設備是終端時，接收端設備可以通過專用訊號接收該至少一組波束對應訊息。Correspondingly, the receiver device receives the message corresponding to the at least one set of beams sent by the transmitter device through a dedicated signal or a broadcast signal. For example, when the transmitting device is an access network device, the receiving device may receive the at least one set of beam corresponding messages through a dedicated signal or a broadcast signal; when the transmitting device is a terminal, the receiving device may receive the at least one signal through a dedicated signal. A set of beams corresponds to the message.

步驟404，接收端設備根據至少一組波束對應訊息，從發送端設備發送的各個波束中選擇接收的波束。Step 404: The receiving device selects a received beam from each beam sent by the transmitting device according to at least one set of beam correspondence messages.

在本發明實施例中，接收某個波束可以是指接收通過該波束傳輸的物理通道中的資料或訊號，相應的，下文涉及的接收某個通道可以是指接收該通道中的資料或訊號。In the embodiment of the present invention, receiving a certain beam may refer to receiving data or signals in a physical channel transmitted through the beam. Accordingly, receiving a certain channel referred to below may refer to receiving data or signals in the channel.

在本發明實施例中，接收端設備根據至少一組波束對應訊息，從發送端設備發送的各個波束中選擇接收的波束的場景，可以包括但不限於以下三種：In the embodiment of the present invention, the scenario where the receiving end device selects a received beam from each beam sent by the transmitting end device according to at least one set of beam correspondence information may include, but is not limited to, the following three scenarios:

第一，接收端設備通過第二波束接收第一物理通道時，可以根據至少一組波束對應訊息，將該第二波束對應的第一波束選擇為用於接收第二物理通道的波束。First, when the receiving end device receives the first physical channel through the second beam, it may select the first beam corresponding to the second beam as a beam for receiving the second physical channel according to at least one set of beam correspondence information.

比如，以第一波束用於傳輸控制通道，第二波束用於傳輸資料通道為例，當接收端設備正在通過一個第二波束接收資料通道時，若接收端設備需要接收控制通道，則可以根據接收到的波束對應訊息快速選擇與該第二波束相對應的第一波束，不需要對發送端設備發送的各個第一波束分別進行測量，從而減少了資料接收過程中對波束的訊號品質進行測量的步驟。For example, taking the first beam for the control channel and the second beam for the data channel as an example, when the receiving device is receiving the data channel through a second beam, if the receiving device needs to receive the control channel, The received beam correspondence information quickly selects the first beam corresponding to the second beam, and does not need to measure each first beam sent by the transmitting device, thereby reducing the measurement of the signal quality of the beam during the data receiving process. A step of.

第二，接收端設備通過第一波束接收第二物理通道時，根據至少一組波束對應訊息，測量該第一波束對應的至少一個第二波束的訊號品質，並將第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為用於接收第一物理通道的波束。Second, when the receiving device receives the second physical channel through the first beam, it measures the signal quality of at least one second beam corresponding to the first beam according to the information corresponding to at least one set of beams, and Among the second beams, the second beam with the best signal quality is selected as a beam for receiving the first physical channel.

比如，以第一波束用於傳輸控制通道，第二波束用於傳輸資料通道為例，當接收端設備正在通過第一波束接收控制通道時，若接收端設備需要接收資料通道，則可以根據接收到的波束對應訊息，確定與第一波束相對應的部分第二波束，並從確定的部分第二波束中選擇出訊號品質最好的第二波束進行資料通道的接收，不需要對發送端設備發送的所有第二波束分別進行測量，從而減少了資料接收過程中對波束的訊號品質進行測量的次數。For example, the first beam is used to transmit the control channel, and the second beam is used to transmit the data channel. For example, when the receiving device is receiving the control channel through the first beam, if the receiving device needs to receive the data channel, it can The received beam corresponds to the message, and a part of the second beam corresponding to the first beam is determined, and the second beam with the best signal quality is selected from the determined part of the second beam for receiving the data channel, and no transmitting device is required. All the second beams sent are measured separately, thereby reducing the number of times that the signal quality of the beam is measured during the data receiving process.

第三，當至少一組波束對應訊息為至少兩組波束對應訊息時，接收端設備測量至少兩組波束對應訊息各自的第一波束的訊號品質，繼而測量至少兩組波束對應訊息各自的第一波束中，訊號品質最好的第一波束對應的至少一個第二波束的訊號品質，並將訊號品質最好的第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為接收的波束。Third, when the at least one set of beam correspondence information is at least two sets of beam correspondence information, the receiving end device measures the signal quality of the first beam of each of the at least two sets of beam correspondence information, and then measures the first of each of the at least two sets of beam correspondence information. Among the beams, the signal quality of at least one second beam corresponding to the first signal with the best signal quality is selected, and the second beam with the best signal quality is selected from the at least one second beam corresponding to the first signal with the best signal quality. Is the received beam.

通過上述方法，當發送端設備向接收端設備所在的方向上發送多個第二波束時，接收端設備不需要對該多個第二波束中的每一個第二波束進行訊號品質的測量，只需要先對覆蓋該多個第二波束的第一波束進行測量，找出其中訊號品質最好的第一波束，而該訊號品質最好的第一波束所覆蓋的至少一個第二波束即可以被認為是訊號品質最好的一組第二波束，接收端設備再對該訊號品質最好的一組第二波束進行測量並選擇出訊號品質最好的第二波束，本方案相比於對每一個第二波束分別進行訊號品質的測量來說，能夠減少資料接收過程中對波束的訊號品質進行測量的次數。With the above method, when the transmitting device sends multiple second beams in the direction where the receiving device is located, the receiving device does not need to perform signal quality measurement on each of the multiple second beams, and only The first beam covering the multiple second beams needs to be measured to find the first beam with the best signal quality, and at least one second beam covered by the first beam with the best signal quality can be detected. It is considered to be the second set of beams with the best signal quality, and the receiving device then measures the second set of beams with the best signal quality and selects the second beam with the best signal quality. For the measurement of the signal quality of one second beam separately, the number of times of measuring the signal quality of the beam during the data receiving process can be reduced.

綜上所述，本發明實施例所示的波束選擇方法，發送端設備將第一波束與第二波束之間的對應關係發送給接收端設備，接收端設備在接收發送端設備發送的資料的過程中，可以根據該第一波束與第二波束之間的對應關係，從發送端設備發送的各個波束中快速選擇接收的波束，減少了資料接收過程中對波束的訊號品質進行測量的步驟或次數，從而減少波束測量所耗費的時間，加速接收端設備的波束測量和選擇的過程，簡化資料接收的複雜度，降低資料接收的時延。In summary, in the beam selection method according to the embodiment of the present invention, the sending device sends the correspondence between the first beam and the second beam to the receiving device, and the receiving device receives the data sent by the sending device. In the process, according to the correspondence between the first beam and the second beam, the received beam can be quickly selected from the beams sent by the transmitting device, reducing the steps of measuring the signal quality of the beam during the data receiving process or This reduces the time spent for beam measurement, speeds up the process of beam measurement and selection at the receiving end device, simplifies the complexity of data reception, and reduces the delay in data reception.

需要說明的是，上述圖4所示實施例中由接收端設備執行的步驟可以單獨實現成為接收端設備側的波束選擇方法，上述各個實施例中由發送端設備執行的步驟可以單獨實現成為發送端設備側的波束選擇方法。It should be noted that the steps performed by the receiving device in the embodiment shown in FIG. 4 may be implemented separately as the beam selection method on the receiving device side, and the steps performed by the transmitting device in the above embodiments may be separately implemented as the transmission Beam selection method on the end device side.

請參考圖5，其示出了本發明一個實施例提供的波束選擇方法的方法流程圖。本實施例以該波束選擇方法應用於圖1所示的移動通訊系統中，發送端設備為接入網設備，接收端設備為終端，且接入網設備通過第二波束發送下行資料通道，通過第一波束發送下行控制通道來舉例說明。該方法包括：Please refer to FIG. 5, which shows a method flowchart of a beam selection method according to an embodiment of the present invention. In this embodiment, the beam selection method is applied to the mobile communication system shown in FIG. 1. The sending end device is an access network device, the receiving end device is a terminal, and the access network device sends a downlink data channel through a second beam. The first beam sends a downlink control channel for illustration. The method includes:

步驟501，接入網設備生成至少一組波束對應訊息，每組波束對應訊息中包含一個第一波束與至少一個第二波束之間的對應關係。Step 501: The access network device generates at least one set of beam correspondence messages, and each set of beam correspondence messages includes a correspondence relationship between a first beam and at least one second beam.

或者，上述第一波束與至少一個第二波束之間的對應關係中也可以包含至少一個第二波束對應的上行物理通道的標識或通道類型，以及，第一波束對應的上行物理通道的標識或通道類型。Alternatively, the correspondence between the first beam and the at least one second beam may also include an identifier or channel type of an uplink physical channel corresponding to the at least one second beam, and an identifier or channel type of the uplink physical channel corresponding to the first beam. Channel type.

步驟502，接入網設備向終端發送至少一組波束訊息。Step 502: The access network device sends at least one set of beam messages to the terminal.

可選的，接入網設備通過專用訊號或廣播訊號發送該至少一組波束對應訊息。Optionally, the access network device sends the message corresponding to the at least one group of beams through a dedicated signal or a broadcast signal.

步驟503，終端接收接入網設備發送的至少一組波束訊息。Step 503: The terminal receives at least one set of beam messages sent by the access network device.

相應的，終端通過專用訊號或廣播訊號接收該至少一組波束對應訊息。Correspondingly, the terminal receives the message corresponding to the at least one set of beams through a dedicated signal or a broadcast signal.

步驟504，終端通過第二波束接收下行資料通道時，將第二波束對應的第一波束選擇為用於接收下行控制通道的波束。Step 504: When the terminal receives the downlink data channel through the second beam, the terminal selects the first beam corresponding to the second beam as a beam for receiving the downlink control channel.

比如，以接入網設備發送的波束如圖2所示為例，接入網設備通過第二波束（波束1至波束4）傳輸下行資料通道，並通過第一波束（波束5和波束6）傳輸下行控制通道，當終端正在通過波束1接收下行資料通道時，此時，若終端需要接收下行控制通道，不需要對波束5和波束6分別進行測量，直接根據接收到的波束對應訊息，快速選擇與波束1相對應的第一波束，即波束5，並通過波束5接收下行控制通道。For example, taking the beam sent by the access network device as shown in FIG. 2 as an example, the access network device transmits the downlink data channel through the second beam (beam 1 to beam 4) and the first beam (beam 5 and beam 6). Transmission of the downlink control channel. When the terminal is receiving the downlink data channel through beam 1, at this time, if the terminal needs to receive the downlink control channel, it is not necessary to measure beam 5 and beam 6, respectively, and directly based on the received beam corresponding information, quickly The first beam corresponding to beam 1 is selected, that is, beam 5, and the downlink control channel is received through beam 5.

綜上所述，本發明實施例提供的波束選擇方法，接入網設備通過第二波束傳輸下行資料通道，通過第一波束傳輸下行控制通道，並向終端通知其發送的第一波束與第二波束之間的對應關係，終端在通過第二波束接收接入網設備傳輸的下行資料通道時，若需要接收下行控制通道，則可以根據第一波束與第二波束之間的對應關係，直接通過該第二波束對應的第一波束接收下行控制通道，不需要對接入網設備發送的各個第一波束進行測量，從而減少了接收下行控制通道過程中，對波束的訊號品質進行測量的步驟。In summary, in the beam selection method provided by the embodiment of the present invention, an access network device transmits a downlink data channel through a second beam, transmits a downlink control channel through a first beam, and notifies a terminal of the first beam and the second beam sent by the terminal. Correspondence between beams. When the terminal receives the downlink data channel transmitted by the access network device through the second beam, if it needs to receive the downlink control channel, it can directly pass the corresponding relationship between the first beam and the second beam. The first beam corresponding to the second beam receives the downlink control channel, and it is not necessary to measure each first beam sent by the access network device, thereby reducing the steps of measuring the signal quality of the beam during the process of receiving the downlink control channel.

在基於圖5的可選實施例中，終端也可以通過接入網設備發送的第一波束與第二波束之間的對應關係，選擇用於接收下行資料通道的第二波束，此時，上述步驟504可以替換實現為步驟504a和步驟504b，如圖6所示：In the optional embodiment based on FIG. 5, the terminal may also select the second beam used to receive the downlink data channel through the correspondence between the first beam and the second beam sent by the access network device. At this time, the above Step 504 may be implemented as steps 504a and 504b, as shown in FIG. 6:

步驟504a，終端通過第一波束接收下行控制通道時，根據至少一組波束對應訊息，測量該第一波束對應的至少一個第二波束的訊號品質。Step 504a: When the terminal receives the downlink control channel through the first beam, the terminal measures the signal quality of at least one second beam corresponding to the first beam according to the information corresponding to the at least one group of beams.

比如，以接入網設備發送的波束如圖2所示為例，接入網設備通過第二波束（波束1至波束4）傳輸下行資料通道，並通過第一波束（波束5和波束6）傳輸下行控制通道，當終端正在通過波束5接收下行控制通道時，此時，若終端需要接收下行資料通道，則根據接收到的波束對應訊息，選擇對與波束5相對應的第二波束（波束1和波束2）進行訊號品質的測量，不需要對波束3和波束4分別進行測量。For example, taking the beam sent by the access network device as shown in FIG. 2 as an example, the access network device transmits the downlink data channel through the second beam (beam 1 to beam 4) and the first beam (beam 5 and beam 6). Transmission of the downlink control channel. When the terminal is receiving the downlink control channel through beam 5, at this time, if the terminal needs to receive the downlink data channel, according to the received beam correspondence message, the second beam (beam corresponding to beam 5 is selected) 1 and beam 2) for signal quality measurement. There is no need to measure beam 3 and beam 4 separately.

步驟504b，終端將第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為用於接收下行資料通道的波束。In step 504b, the terminal selects, among at least one second beam corresponding to the first beam, the second beam with the best signal quality as a beam for receiving a downlink data channel.

比如，終端對波束1和波束2分別進行訊號品質的測量後，選擇通過波束1和波束2中訊號品質最好的波束接收下行資料通道。For example, after the terminal measures the signal quality of beam 1 and beam 2 respectively, the terminal selects to receive the downlink data channel through the beam with the best signal quality in beam 1 and beam 2.

綜上所述，本發明實施例提供的波束選擇方法，接入網設備通過第二波束傳輸下行資料通道，通過第一波束傳輸下行控制通道，並向終端通知其發送的第一波束與第二波束之間的對應關係，終端在通過第一波束接收接入網設備傳輸的下行控制通道時，若需要接收下行資料通道，則可以根據第一波束與第二波束之間的對應關係，僅對第一波束對應的第二波束進行測量，不需要對接入網設備發送的所有第二波束分別進行測量，從而減少了接收下行資料通道中的資料過程中，對波束的訊號品質進行測量的次數。In summary, in the beam selection method provided by the embodiment of the present invention, an access network device transmits a downlink data channel through a second beam, transmits a downlink control channel through a first beam, and notifies a terminal of the first beam and the second beam sent by the terminal. Correspondence between the beams. When the terminal receives the downlink control channel transmitted by the access network device through the first beam, if it needs to receive the downlink data channel, it can only use the corresponding relationship between the first beam and the second beam. The second beam corresponding to the first beam is measured, and it is not necessary to separately measure all the second beams sent by the access network device, thereby reducing the number of times that the signal quality of the beam is measured during receiving data in the downlink data channel. .

請參考圖7，其示出了本發明一個實施例提供的波束選擇方法的方法流程圖。本實施例以該波束選擇方法應用於圖1所示的移動通訊系統中，發送端設備為接入網設備，接收端設備為終端來舉例說明。該方法包括：Please refer to FIG. 7, which shows a method flowchart of a beam selection method according to an embodiment of the present invention. In this embodiment, the beam selection method is applied to the mobile communication system shown in FIG. 1, and the sending end device is an access network device and the receiving end device is a terminal. The method includes:

步驟701，接入網設備生成至少兩組波束對應訊息，每組波束對應訊息中包含一個第一波束與至少一個第二波束之間的對應關係。Step 701: The access network device generates at least two sets of beam correspondence messages, and each set of beam correspondence messages includes a correspondence between a first beam and at least one second beam.

在本發明實施例中，第一波束可以不對應特定的下行物理通道。比如，不同的下行物理通道都可以通過第一波束或者第二波束進行傳輸。In the embodiment of the present invention, the first beam may not correspond to a specific downlink physical channel. For example, different downlink physical channels can be transmitted through the first beam or the second beam.

或者，與圖5或圖6所示的實施例類似的，在本發明實施例中，第一波束和第二波束也可以分別用於傳輸不同的下行物理通道。Alternatively, similar to the embodiment shown in FIG. 5 or FIG. 6, in the embodiment of the present invention, the first beam and the second beam may also be used to transmit different downlink physical channels, respectively.

步驟702，接入網設備向終端發送生成的至少兩組波束訊息。Step 702: The access network device sends at least two sets of beam messages generated to the terminal.

步驟703，終端接收發送端設備發送的至少兩組波束訊息。Step 703: The terminal receives at least two sets of beam messages sent by the sending-end device.

步驟704，終端測量至少兩組波束對應訊息各自的第一波束的訊號品質。Step 704: The terminal measures the signal quality of the first beam of each message corresponding to the at least two sets of beams.

比如，以接入網設備發送的波束如圖3所示為例，接入網設備發送波束1至波束9這9個第二波束，終端需要通過第二波束接收接入網設備發送的訊號或資料時，需要從波束1至波束9中選擇出訊號品質最好的第二波束。通過本發明實施例所示的方案，終端接收到接入網設備發送的波束對應訊息後，在選擇接收的第二波束時，可以先測量與9個第二波束相對應的3個第一波束的訊號品質，即對圖3中的波束10、波束11和波束12的訊號品質進行測量。For example, taking the beam sent by the access network device as shown in FIG. 3 as an example, the access network device sends 9 second beams, beams 1 to 9, and the terminal needs to receive a signal or For data, a second beam with the best signal quality needs to be selected from beams 1 to 9. With the solution shown in the embodiment of the present invention, after the terminal receives the beam corresponding message sent by the access network device, when the terminal selects the received second beam, it can first measure 3 first beams corresponding to 9 second beams. The signal quality is measured by measuring the signal quality of the beams 10, 11 and 12 in FIG. 3.

步驟705，終端測量至少兩組波束對應訊息各自的第一波束中，訊號品質最好的第一波束對應的至少一個第二波束的訊號品質。In step 705, the terminal measures the signal quality of at least one second beam corresponding to the first signal with the best signal quality among the respective first beams of the messages corresponding to the at least two sets of beams.

終端對圖3中的波束10、波束11和波束12的訊號品質進行測量後，確定其中訊號品質最好的第一波束，比如，假設確定出的訊號品質最好的第一波束為波束11，則進一步的，終端對波束11對應3個第二波束（即波束4至波束6）進行訊號品質的測量。After the terminal measures the signal quality of the beams 10, 11 and 12 in FIG. 3, the terminal determines the first beam with the best signal quality. For example, if the determined first beam with the best signal quality is the beam 11, Further, the terminal performs signal quality measurement on the beam 11 corresponding to the three second beams (ie, beam 4 to beam 6).

步驟706，終端將訊號品質最好的第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為接收的波束。Step 706: The terminal selects the second beam with the best signal quality among the at least one second beam corresponding to the first beam with the best signal quality as the received beam.

具體的，終端可以將上述訊號品質最好的第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為用來接收接入網設備發送的資料或訊號的波束。Specifically, the terminal may select at least one second beam corresponding to the first beam with the best signal quality, and the second beam with the best signal quality is the beam used to receive data or signals sent by the access network device.

比如，終端對與訊號品質最好的第一波束相對應的第二波束（即圖3中的波束4至波束6）的訊號品質進行測量後，可以選擇接收波束4至波束6中訊號品質最好的波束，並通過選擇出的波束接收接入網設備發送的資料或訊號。For example, after measuring the signal quality of the second beam (ie, beams 4 to 6 in FIG. 3) corresponding to the first beam with the best signal quality, the terminal may choose to receive the best signal quality among beams 4 to 6. A good beam, and receive the data or signal sent by the access network device through the selected beam.

具體例如，以波束對應訊息中包含第一波束的參考訊號與對應的各個第二波束的參考訊號之間的對應關係為例，終端可以根據波束10、波束11和波束12的參考訊號，測量波束10、波束11和波束12的訊號品質，在確定出這三者中的波束11的訊號品質最好之後，查詢獲得波束11的參考訊號與波束4至波束6的參考訊號之間的對應關係，並根據波束4至波束6的參考訊號，測量波束4至波束6的訊號品質，從中選擇出訊號品質最好的第二波束。For example, taking the correspondence between the reference signal of the first beam and the corresponding reference signal of each second beam as an example in the beam correspondence message, the terminal may measure the beam according to the reference signals of the beam 10, the beam 11, and the beam 12 10. The signal quality of the beam 11 and the beam 12, after determining that the signal quality of the beam 11 among the three is the best, query to obtain the correspondence between the reference signal of the beam 11 and the reference signal of the beam 4 to beam 6, And according to the reference signals of beams 4 to 6, the signal quality of beams 4 to 6 is measured, and the second beam with the best signal quality is selected from them.

在本發明實施例的上述過程中，終端從圖3所示的9個第二波束中選擇出一個第二波束時，只需要先對3個第一波束進行測量，再對訊號品質最好的第一波束對應的3個第二波束進行測量，前後經過6次測量即可以確定出接收的第二波束，不需要對9個第二波束分別進行一次測量。In the above process of the embodiment of the present invention, when the terminal selects a second beam from the nine second beams shown in FIG. 3, it only needs to measure the three first beams first, and then the one with the best signal quality The three second beams corresponding to the first beam are measured, and the second beam received can be determined after 6 measurements before and after, and it is not necessary to perform one measurement for each of the 9 second beams.

綜上所述，本發明實施例提供的波束選擇方法，接入網設備向終端通知其發送的第一波束與第二波束之間的對應關係，終端從接入網設備發送的各個第二波束中選擇一個第二波束進行接收時，只需要先對接入網設備發送的各個第一波束進行測量，再對其中訊號品質最好的第一波束所對應的第二波束進行測量，即可以確定出接收的第二波束，不需要對接入網設備發送的所有第二波束分別進行測量，從而減少了通過第二波束接收資料或訊號的過程中，對波束的訊號品質進行測量的次數。In summary, in the beam selection method provided in the embodiment of the present invention, the access network device notifies the terminal of the correspondence between the first beam and the second beam it sends, and each second beam sent by the terminal from the access network device When selecting a second beam for reception in the network, you only need to measure each first beam sent by the access network device, and then measure the second beam corresponding to the first beam with the best signal quality. The received second beam does not need to be measured separately for all the second beams sent by the access network device, thereby reducing the number of times that the signal quality of the beam is measured during the process of receiving data or signals through the second beam.

上述圖5至圖7所示的方案均以發送端設備為接入網設備，接收端設備為終端為例進行說明。本發明提供的波束選擇方法，同樣適用於接入網設備對終端發送的波束進行選擇的情形。The foregoing solutions shown in FIG. 5 to FIG. 7 are described by using a sending end device as an access network device and a receiving end device as a terminal as an example. The beam selection method provided by the present invention is also applicable to a situation where an access network device selects a beam sent by a terminal.

請參考圖8，其示出了本發明一個實施例提供的波束選擇方法的方法流程圖。本實施例以該波束選擇方法應用於圖1所示的移動通訊系統中，發送端設備為終端，接收端設備為接入網設備，且終端通過第二波束發送上行資料通道，通過第一波束發送上行控制通道來舉例說明。該方法包括：Please refer to FIG. 8, which shows a method flowchart of a beam selection method according to an embodiment of the present invention. In this embodiment, the beam selection method is applied to the mobile communication system shown in FIG. 1. The sending end device is a terminal, the receiving end device is an access network device, and the terminal sends an uplink data channel through a second beam, and passes the first beam. Send an uplink control channel as an example. The method includes:

步驟801，終端生成至少一組波束對應訊息，每組波束對應訊息中包含一個第一波束與至少一個第二波束之間的對應關係。Step 801: The terminal generates at least one set of beam correspondence information, and each set of beam correspondence information includes a correspondence relationship between a first beam and at least one second beam.

可選的，在本發明實施例中，上述第一波束與至少一個第二波束之間的對應關係中還包含至少一個第二波束對應的上行資料通道，以及，第一波束對應的上行控制通道。Optionally, in the embodiment of the present invention, the correspondence between the first beam and the at least one second beam further includes an uplink data channel corresponding to the at least one second beam, and an uplink control channel corresponding to the first beam. .

步驟802，終端向接入網設備發送至少一組波束訊息。Step 802: The terminal sends at least one set of beam messages to the access network device.

可選的，終端通過專用訊號，比如無線資源控制（Radio Resource Control，RRC）訊號，發送該至少一組波束對應訊息。Optionally, the terminal sends the message corresponding to the at least one group of beams through a dedicated signal, such as a Radio Resource Control (RRC) signal.

步驟803，接入網設備接收終端發送的至少一組波束訊息。Step 803: The access network device receives at least one set of beam messages sent by the terminal.

相應的，接入網設備通過專用訊號接收終端發送的該至少一組波束對應訊息。Correspondingly, the access network device receives the message corresponding to the at least one set of beams sent by the terminal through a dedicated signal.

步驟804，接入網設備通過第二波束接收上行資料通道時，將第二波束對應的第一波束選擇為用於接收上行控制通道的波束。Step 804: When the access network device receives the uplink data channel through the second beam, the first beam corresponding to the second beam is selected as the beam for receiving the uplink control channel.

比如，以終端發送的波束如圖2所示為例，終端通過第二波束（波束1至波束4）傳輸上行資料通道，並通過第一波束（波束5和波束6）傳輸上行控制通道，當接入網設備正在通過波束1（即上述第一第二波束）接收上行資料通道時，此時，若接入網設備需要接收上行控制通道，則不需要對波束5和波束6分別進行測量，直接根據接收到的波束對應訊息，快速選擇與波束1相對應的第一波束（波束5），並通過波束5接收上行控制通道。For example, taking the beam sent by the terminal as shown in FIG. 2 as an example, the terminal transmits the uplink data channel through the second beam (beam 1 to beam 4) and the uplink control channel through the first beam (beam 5 and beam 6). When the access network device is receiving the uplink data channel through beam 1 (that is, the first and second beams described above), at this time, if the access network device needs to receive the uplink control channel, it is not necessary to separately measure beam 5 and beam 6, Directly select the first beam (beam 5) corresponding to beam 1 directly according to the received beam correspondence information, and receive the uplink control channel through beam 5.

綜上所述，本發明實施例提供的波束選擇方法，終端通過第二波束傳輸上行資料通道，通過第一波束傳輸上行控制通道，並向接入網設備通知其發送的第一波束與第二波束之間的對應關係，接入網設備在通過第二波束接收終端傳輸的上行資料通道時，若需要接收上行控制通道，則可以根據第一波束與第二波束之間的對應關係，直接通過第二波束對應的第一波束接收上行控制通道，不需要對終端發送的各個第一波束進行測量，從而減少了接收上行控制通道中的資料過程中，對波束的訊號品質進行測量的步驟。In summary, in the beam selection method provided by the embodiment of the present invention, a terminal transmits an uplink data channel through a second beam, transmits an uplink control channel through a first beam, and notifies an access network device of the first beam and the second beam sent by the access network device. Correspondence between the beams. When the access network device receives the uplink data channel transmitted by the terminal through the second beam, if it needs to receive the uplink control channel, it can directly pass through the correspondence between the first beam and the second beam. The first beam corresponding to the second beam receives the uplink control channel, and does not need to measure each first beam sent by the terminal, thereby reducing the steps of measuring the signal quality of the beam during the process of receiving data in the uplink control channel.

在基於圖8的可選實施例中，終端也可以通過接入網設備發送的第一波束與第二波束之間的對應關係，選擇用於接收下行資料通道的第二波束，此時，上述步驟804可以替換實現為步驟804a和步驟804b，如圖9所示：In the optional embodiment based on FIG. 8, the terminal may also select the second beam used to receive the downlink data channel through the correspondence between the first beam and the second beam sent by the access network device. Step 804 can be implemented as steps 804a and 804b, as shown in FIG. 9:

比如，以終端發送的波束如圖2所示為例，終端通過第二波束（波束1至波束4）傳輸上行資料通道，並通過第一波束（波束5和波束6）傳輸上行控制通道，當接入網設備正在通過波束5接收上行控制通道時，此時，若需要接收上行資料通道，則可以根據接收到的波束對應訊息，選擇對與波束5相對應的第二波束（波束1和波束2）進行訊號品質的測量，不需要對波束3和波束4分別進行測量。For example, taking the beam sent by the terminal as shown in FIG. 2 as an example, the terminal transmits the uplink data channel through the second beam (beam 1 to beam 4) and the uplink control channel through the first beam (beam 5 and beam 6). When the access network device is receiving the uplink control channel through beam 5, at this time, if it needs to receive the uplink data channel, it can select the second beam (beam 1 and beam) corresponding to beam 5 according to the received beam correspondence information. 2) For signal quality measurement, it is not necessary to measure beam 3 and beam 4 separately.

步驟804b，接入網設備將第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為用於接收上行資料通道的波束。In step 804b, the access network device selects the second beam with the best signal quality among the at least one second beam corresponding to the first beam as the beam for receiving the uplink data channel.

比如，以圖2所示為例，接入網設備對波束1和波束2分別進行訊號品質的測量後，選擇通過波束1和波束2中訊號品質最好的波束接收上行資料通道。For example, as shown in FIG. 2, after the access network device measures the signal quality of beam 1 and beam 2 respectively, it selects to receive the uplink data channel through the beam with the best signal quality in beam 1 and beam 2.

綜上所述，本發明實施例提供的波束選擇方法，終端通過第二波束傳輸下行資料通道，通過第一波束傳輸下行控制通道，並向接入網設備通知其發送的第一波束與第二波束之間的對應關係，接入網設備在通過第一波束接收終端傳輸的上行控制通道時，若需要接收上行資料通道，則可以根據第一波束與第二波束之間的對應關係，僅對第一波束對應的第二波束進行測量，不需要對終端發送的所有第二波束分別進行測量，從而減少了接收上行資料通道的過程中，對波束的訊號品質進行測量的次數。In summary, in the beam selection method provided by the embodiment of the present invention, a terminal transmits a downlink data channel through a second beam, transmits a downlink control channel through a first beam, and notifies an access network device of the first beam and the second beam sent by the access network device. Correspondence between beams. When the access network device receives the uplink data channel transmitted by the terminal through the first beam, if it needs to receive the uplink data channel, it can only use the corresponding relationship between the first beam and the second beam. The second beam corresponding to the first beam is measured, and it is not necessary to separately measure all the second beams sent by the terminal, thereby reducing the number of times that the signal quality of the beam is measured during the process of receiving the uplink data channel.

請參考圖10，其示出了本發明一個實施例提供的波束選擇方法的方法流程圖。本實施例以該波束選擇方法應用於圖1所示的移動通訊系統中，發送端設備為終端，接收端設備為接入網設備來舉例說明。該方法包括：Please refer to FIG. 10, which illustrates a method flowchart of a beam selection method according to an embodiment of the present invention. In this embodiment, the beam selection method is applied to the mobile communication system shown in FIG. 1, and the sending end device is a terminal and the receiving end device is an access network device. The method includes:

步驟1001，終端生成至少兩組波束對應訊息，每組波束對應訊息中包含一個第一波束與至少一個第二波束之間的對應關係。Step 1001: The terminal generates at least two sets of beam correspondence messages, and each set of beam correspondence messages includes a correspondence relationship between a first beam and at least one second beam.

在本發明實施例中，第一波束可以不對應特定的上行物理通道。比如，不同的上行物理通道都可以通過第一波束或者第二波束進行傳輸。In the embodiment of the present invention, the first beam may not correspond to a specific uplink physical channel. For example, different uplink physical channels can be transmitted through the first beam or the second beam.

或者，與圖8或圖9所示的實施例類似的，在本發明實施例中，第一波束和第二波束也可以分別用於傳輸不同的上行物理通道。Alternatively, similar to the embodiment shown in FIG. 8 or FIG. 9, in this embodiment of the present invention, the first beam and the second beam may also be used to transmit different uplink physical channels, respectively.

步驟1002，終端向接入網設備發送至少兩組波束訊息。Step 1002: The terminal sends at least two sets of beam messages to the access network device.

可選的，終端通過專用訊號發送該至少一組波束對應訊息。Optionally, the terminal sends the at least one set of beam corresponding messages through a dedicated signal.

步驟1003，接入網設備接收終端發送的至少兩組波束訊息。Step 1003: The access network device receives at least two sets of beam messages sent by the terminal.

步驟1004，接入網設備測量至少兩組波束對應訊息各自的第一波束的訊號品質。Step 1004: The access network device measures the signal quality of the first beam of each message corresponding to the at least two sets of beams.

比如，以終端發送的波束如圖3所示為例，終端發送波束1至波束9這9個第二波束，接入網設備需要通過第二波束接收終端發送的訊號或資料時，需要從波束1至波束9中選擇出訊號品質最好的第二波束。通過本發明實施例所示的方案，接入網設備在選擇第二波束時，可以先測量與9個第二波束相對應的3個第一波束的訊號品質，即對圖3中的波束10、波束11和波束12的訊號品質進行測量。For example, taking the beam transmitted by the terminal as shown in FIG. 3 as an example, the terminal sends 9 second beams, beam 1 to beam 9. When the access network device needs to receive the signal or data sent by the terminal through the second beam, it needs to transmit the beam The second beam with the best signal quality is selected from 1 to beam 9. With the solution shown in the embodiment of the present invention, when the access network device selects the second beam, it can first measure the signal quality of the three first beams corresponding to the nine second beams, that is, to the beam 10 in FIG. 3 , Beam 11 and beam 12 are measured.

步驟1005，接入網設備測量至少兩組波束對應訊息各自的第一波束中，訊號品質最好的第一波束對應的至少一個第二波束的訊號品質。Step 1005: The access network device measures the signal quality of at least one second beam corresponding to the first signal with the best signal quality among the respective first beams of the messages corresponding to the at least two sets of beams.

接入網設備對圖3中的波束10、波束11和波束12的訊號品質進行測量後，確定其中訊號品質最好的第一波束，比如，假設確定出的第一波束為波束11，則進一步的，接入網設備對波束11對應的3個第二波束（即波束4至波束6）進行訊號品質的測量。After the access network device measures the signal quality of beam 10, beam 11 and beam 12 in FIG. 3, it determines the first beam with the best signal quality. For example, if the determined first beam is beam 11, then , The access network device performs signal quality measurement on the three second beams corresponding to the beam 11 (that is, beams 4 to 6).

步驟1006，接入網設備將該訊號品質最好的第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為接收的波束。Step 1006: The access network device selects the second beam with the best signal quality among the at least one second beam corresponding to the first beam with the best signal quality as the received beam.

具體的，接入網設備可以將上述訊號品質最好的第一波束對應的至少一個第二波束中，訊號品質最好的第二波束選擇為用來接收終端發送的資料或訊號的波束。Specifically, the access network device may select at least one second beam corresponding to the first beam with the best signal quality, and the second beam with the best signal quality is a beam used to receive data or signals sent by the terminal.

比如，接入網設備對圖3中的波束4至波束6的訊號品質進行測量後，選擇波束4至波束6中訊號品質最好的波束作為用於接收資料或訊號的波束。For example, after the access network device measures the signal quality of beams 4 to 6 in FIG. 3, it selects the beam with the best signal quality among beams 4 to 6 as the beam for receiving data or signals.

在本發明實施例的上述過程中，接入網設備從圖3所示的9個第二波束中選擇出一個第二波束時，只需要先對3個第一波束進行測量，再對訊號品質最好的第一波束對應的3個第二波束進行測量，前後經過6次測量即可以確定出接收的第二波束，不需要對9個第二波束分別進行一次測量。In the above process of the embodiment of the present invention, when the access network device selects a second beam from the nine second beams shown in FIG. 3, it only needs to measure the three first beams first, and then the signal quality The best first beam corresponds to 3 second beams to be measured. After 6 measurements, the received second beam can be determined. It is not necessary to perform a single measurement for each of the 9 second beams.

綜上所述，本發明實施例提供的波束選擇方法，終端向接入網設備通知其發送的第一波束與第二波束之間的對應關係，接入網設備從終端發送的各個第二波束中選擇一個第二波束進行接收時，只需要先對終端發送的各個第一波束進行測量，再對其中訊號品質最好的第一波束所對應的第二波束進行測量，即可以確定出接收的第二波束，不需要對終端發送的所有第二波束分別進行測量，從而減少了通過第二波束接收資料或訊號的過程中，對波束的訊號品質進行測量的次數。In summary, in the beam selection method provided by the embodiment of the present invention, the terminal notifies the access network device of the correspondence between the first beam and the second beam it sends, and each second beam sent by the access network device from the terminal. When selecting a second beam for reception, you only need to measure each first beam sent by the terminal first, and then measure the second beam corresponding to the first beam with the best signal quality to determine the received signal. The second beam does not need to separately measure all the second beams sent by the terminal, thereby reducing the number of times that the signal quality of the beam is measured during the process of receiving data or signals through the second beam.

需要說明的是，上述圖5至圖10所示的各個實施例中由接入網設備執行的步驟可以單獨實現成為接入網設備側的波束選擇方法，上述圖5至圖10所示的各個實施例中由終端執行的步驟可以單獨實現成為終端側的波束選擇方法。It should be noted that the steps performed by the access network device in the embodiments shown in FIG. 5 to FIG. 10 described above can be implemented separately as the beam selection method on the access network device side. The steps performed by the terminal in the embodiments may be implemented separately as a method of beam selection on the terminal side.
